Passing List of Objects to Fragment
14,883
You can pass List<Human>
as Parcelable
ArrayList
to the Bundle as follows:
companion object {
fun newInstance(myList : ArrayList<Human>): MyFragment {
val args = Bundle()
args.putParcelableArrayList("list",myList);
val fragment = MyFragment()
fragment.arguments = args
return fragment
}
}
To retrieve data:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val args = arguments
var myList : ArrayList<Human> = args.getParcelableArrayList<Human>("list")
}
Do Parcelable
implementation in Human
Data Class :
data class Human(val name: String, val phone: String) : Parcelable {
constructor(parcel: Parcel) : this(
parcel.readString(),
parcel.readString()) {
}
override fun writeToParcel(dest: Parcel?, flags: Int) {
TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
}
override fun describeContents(): Int {
TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
}
companion object CREATOR : Parcelable.Creator<Human> {
override fun createFromParcel(parcel: Parcel): Human {
return Human(parcel)
}
override fun newArray(size: Int): Array<Human?> {
return arrayOfNulls(size)
}
}
}

class CholesterolPagingFragment: Fragment() { companion object { fun newInstance(): CholesterolPagingFragment { val args = Bundle() val fragment = CholesterolPagingFragment() fragment.arguments = args return fragment } } override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? { val view = inflater.inflate(R.layout.fragment_paging_cholesterol, container, false) return view } }
I have wrote the above code in Kotlin to initialize a fragment. Though I can't figure out a way to pass a list of objects(eg:
List<Human>
) to this fragment. I have tried with theBundle()
but couldn't find a proper way.
